Add better airway support, fix various issues with VIA, and add
parsing / generation of ICAO route strings. Also fix the
serialisation of flight-plans with airway enroute segments, so these
can be restored correctly.
Upcoming flight-planning changes want to use the perf computation code
in route-path, so move it to a public class, and implement some of the
missing functionality, especially correct GS computation for altitude.
The extractBits(), signExtend(), and writeBits() functions of the anonymous
namespace in Input/FGHIDEventInput.cxx have been shifted out of the namespace
and are now exposed via the header. This is needed as
<Input/FGHIDEventInput.cxx> cannot be imported within the CppUnit
infrastructure, as it is already built into the run_test_suite binary.
The test_suite/helpers directory has been renamed to test_suite/FGTestApi/ and
all the fgtest namespaces renamed to FGTestApi. The helper functions are now
also placed into either a setUp or tearDown namespace depending on their
function. And a new FGTestApi::PrivateAccessor::FDM namespace has been created
for holding friend classes used to access private or protected variables or
functions from solely within the test suite.
This required many time related include files, functions, and variables to be
tested for via CMake, and converted to macros via #cmakedefine, so that they
would be automatically set for the test-mktime.cxx file.
This includes the basic CMake infrastructure for building and executing the test
suite. Four test categories have been added - unit, system/functional, GUI, and
simgear unit tests. The test suite is run by typing 'make test_suite'.
All of the fgfs sources are included in the new run_test_suite executable,
excluding the bootstrap routine and its main() function. The test suite
currently consists of a single dummy unit test for the NasalSys subsystem, and a
single demonstration simgear/props unit test.
